The fact that stores like ArtPrimo still carry this ink,definately says something about the quality of it.Back in my early years of writing,(1992-no internet)I had heard of Marsh and Garvey,but had no idea where to buy it.One of my local stores in downtown New Bedford,Ma. carried pilots and uni-s and I found out the old lady there could order bottles of Pilot and call me when they came in.After that,Pilot ink was all I ever used for about 8 years. In 2011,this ink is still competing with inks that are made for writers and still one of the best.
